In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 XT Crossfire are noticeably better than the AMD Radeon HD 7970 MSI OC Edition.

The HD 7970 has a 85 MHz higher core clock speed than the HD 7870 XT, but the HD 7870 XT has 64 more Texture Mapping Units than the HD 7970. As a result, the HD 7870 XT exhibits a 48.3 GTexel/s better Texture Fill Rate than the HD 7970. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7970 has a 85 MHz higher core clock speed than the HD 7870 XT, but the HD 7870 XT has 32 more Render Output Units than the HD 7970. As a result, the HD 7870 XT exhibits a 26.9 GPixel/s better Pixel Fill Rate than the HD 7970. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 XT was released less than a year after the HD 7970, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 7870 XT has 1024 MB more video memory than the HD 7970, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 XT also has superior memory performance overall.

The HD 7870 XT has 120 GB/sec greater memory bandwidth than the HD 7970, which means that the memory performance of the HD 7870 XT is massively better than the HD 7970.

The Radeon HD 7870 XT Crossfire has 3072 Shader Processing Units and the Radeon HD 7970 MSI OC Edition has 2048. However, the actual shader performance of the HD 7870 XT is 2415 and the actual shader performance of the HD 7970 is 1758. The HD 7870 XT having 657 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 XT delivers a massively smoother and more efficient experience when processing graphical data than the HD 7970.

The Radeon HD 7870 XT Crossfire requires 350 Watts to run but there is no entry for the Radeon HD 7970 MSI OC Edition. We would recommend a PSU with at least 750 Watts for the HD 7870 XT and a PSU with at least 550 Watts for the HD 7970. The HD 7870 XT has been recommended a PSU with 200 Watts more than the HD 7970. The difference is significant enough that the HD 7870 XT may have an adverse affect on your yearly electricity bills in comparison to the HD 7970.

GPU Mini Review

Mini ReviewRadeon HD 7870 XT Crossfire is a solution of two Radeon HD 7870 XT put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7870 XT to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is close to Radeon HD 7950 Crossfire but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7870 XT. Expect this combination to draw up to 370 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
Radeon HD 7970 MSI OC Edition is a special Edition of the Radeon HD 7970. See the page of the standard edition for more information.
It features overclocking out of the box in the core-clock which went from 925MHz to 1010MHz.
Benchmarks indicate a 3% performance boost when compared to the standard Radeon HD 7970.
Therefore, all games, including very demanding ones, should be fully playable at max settings and with very attractive resolutions.
